Following description of this unreleased game from: atariprotos
Bugs Bunny was probably supposed to be part of Atari's Children's series, but was shelved in favor of Snoopy and the Red Baron after Snoopy tested better. Snoopy probably got the nod because its a fast paced shooting game and Bugs Bunny is more of an action game that's played in spurts. This isn't to say that Bugs Bunny is a bad game, it's just different.
As the title suggests, you control Bugs Bunny who has been rudely awakened from his slumber by Elmer Fudd and his rabbit sniffing hound. Each level the hound will dig up a carrot causing our pal Bugs Bunny to appear. Bugs must quickly run and jump in the hole that appears where the carrot was before he's shot by Elmer. This is actually alot harder than it sounds since it takes some skill to get Bugs lined up with the hole. To help you out a bit, the left difficulty switch can be used to make the hole wider or smaller, while the right difficulty switch controls how fast Elmer shoots.
